What's New


Still Advancing

We’ve been as busy as usual since our last update, but are experiencing a few necessary work delays associated with responsible reactions to the pandemic. Many of our contracts are deemed “essential” due to DoD, infrastructure construction and environmental remediation components, so we’re still plugging along using appropriate PPE and “social distancing” protocols.

Recent survey capability upgrades have included acquisition of a terrestrial LiDAR system (boat or vehicle mounted); a USBL tracking system; FAA sUAV (drone) licensure for aerial surveys used on environmental monitoring projects (including full 3D photogrammetric capabilities); acquisition of a new IxBlue Octans motion and heading sensor; and major upgrades to underwater video and coring systems. All upgrades were specifically selected to ease installation on vessels-of-opportunity.

Noteworthy projects since our last post have included: continued support for our clients, US ACOE and US EPA on offshore disposal monitoring projects at the NY Historic Area Remediation Site (HARS) and DAMOS Sites; organization and implementation of an AUV-based synthetic aperture sonar survey at the Massachusetts Bay Disposal Site; ongoing hydrographic survey and QC support for the final stages of the New Bedford Harbor CERCLA site remediation; mapping (acoustic and video) monitoring of eelgrass meadows along cable crossings and at State and private project sites; bathymetric surveys and volumetric analysis of scores of reservoirs throughout the northeast; and hydrographic QC/modeling support for large-scale offshore wind turbine development efforts. We’ve continued to participate in dozens of smaller-scale environmental sampling and hydrographic/geophysical mapping projects. We’ve been collaborating with a large engineering firm and tasked with time series comparisons of topobathymetric LiDAR data to monitor salt marsh losses in Jamaica Bay (NYC).

Current multi-year projects include work on:

- New England and NY District USACE multibeam monitoring of offshore dredged material disposal sites;

- NYCEDC on-call maritime engineering services (including hydrographic surveys, underwater, subsurface inspections, environmental studies, and sediment cores);

- Biannual nearshore underwater video monitoring for beach nourishment projects;

- Site characterization (bathymetry and sediment sampling) at Superfund Sites in RI and MA.


NOAA RNC Tile Service displays first ENC-only product,

CR is proud to have contributed to this important mapping effort. The lower Merrimack River is a beautiful natural resource with an important and economically significant history.

Lower Merrimack River


Collaborative effort to create new nautical chart returns recreational boaters to Haverhill, Massachusetts,

Working under contract to the Greater Haverhill Foundation, CR performed bathymetric and side scan sonar surveys of an approximately eight mile reach of the Merrimack River between Merrimac and Haverhill, Massachusetts in 2014. NOAA's Office of Coast Survey merged the 2014 data with ACOE multibeam data (2004) and NOAA LiDAR data to construct a 1:12,000 chart of the river from Newburyport to downtown Haverhill. We're proud to have contributed to this economically important charting effort.

Environmental/Oceanographic Technician

CR Environmental, Inc. is seeking a scientist/oceanographic technician to perform marine and fresh water survey and sampling operations. An Environmental Sciences background and basic mechanical, electronic, and boating skills are required. The applicant should have experience performing coastal survey and sampling operations, such as bathymetric and geophysical mapping, sediment sampling, and water quality monitoring. The applicant must have strong computer skills, including Windows networking experience, and be interested in the operation of navigation, survey equipment, and associated survey software. Responsibilities will include data processing and report preparation. Survey training will be provided for qualified applicants. Contact Chip Ryther or Charlotte Cogswell at 508-563-7970. chip@crenvironmental.com

CR took delivery of the 25-foot purpose-built Hydrographic Survey Vessel, R/V Cyprinodon, in August, 2016. We've since deployed Cyprinodon on several multibeam surveys from Connecticut to Maine using our R2 Sonic "Sonic 2022" system (upgraded to 700-kHz), single-beam bathymetric surveys, side-scan surveys, underwater video mapping of eelgrass and a challenging ADCP survey. The vessel has performed without fault on each mission. Importantly, she's got great seats and a heated pilot house! We look forward to welcoming you aboard.


Overdue Update!

Thanks to our wonderful clients, it's been a busy few years. We are grateful!

Captain Ben Maher joined CR in 2014 and has proven himself to be an outstanding navigator, shallow water hydrographer and environmental technician.

In the Spring of 2015, we added an R2 Sonic "Sonic 2022" multi beam system and an IxBlue Octans heading/motion system to our equipment pool. These were followed by upgrades to CR's CTD and SVP collection with an AML Minos-X SVP, YSI Castaway and YSI ProDSS. Additional state-of-the-art RTK GPS systems have been added to our hydrographic and wetlands equipment pools.

In 2015, CR conducted the Massachusetts portion of EPA's National Coastal Condition Assessment (NCAA) under contract to MA CZM. The project involved intensive sediment and water sampling at more than 50 sites which spanned the entire Massachusetts coastline.

CR has continued to conduct several variable-scale hydrographic surveys per year for the US ACE DAMOS Program. Since our last update, we've also conducted three multibeam surveys at the NY Bight HARS site with a line-mile total approaching 2,300. We're particularly appreciative of the extraordinary hospitality afforded by the folks at the Blue Bay Inn of Atlantic Highlands, NJ.

Other challenging hydrographic or environmental investigations since our last update seem innumerable. We're proud to provide continuing support for the Superfund (CERCLA) remediation efforts at New Bedford Harbor, MA and Onondaga Lake, NY, amongst many others. Re-visiting the Gilboa Dam (Schoharie Reservoir, NY) in support of rebuilding and tunneling efforts with our new multibeam system was particularly rewarding after a 19-year intermission. The views of the Palisades from Lophius on the Hudson River were thoroughly appreciated. Tasks supporting water supply reservoirs have been the icing!

CR takes ownership of Odom MB1 and put it to the test in New York City

In late December, CR took ownership of an Odom MB1 multibeam sonar system, and immediately put it to use on the R/V Lophius surveying in Brooklyn and Queens. The survey was designed to map impacts from hurricane Sandy, which impacted the greater New York Harbor area in October. The MB1 performed incredibly well, providing soundings in as shallow as 4 feet of water while maintaining ACOE-specified accuracy levels.
